MANTLE-SUPPORT.

Specification of Letters Patent.

Patented Jan. 30, 1906.

To 1r/ZZ whom it may concern:

Be it known that I, TOWNSEND STITEs, a citizen of the United States,residing at Gloucester City, in the county of Camden and State of NewJersey, have invented a certain new and useful Mantle-Support, of whichthe following is a specification,

Objects of the present invention are to provide a mantle-carrier whichis complete in itself and is adapted to be transported along with themantle and applied as a unit for use in connection with burners of highheating power, to make impossible the bending of the supporting-Wire,and to provide for properly supporting the refractory magnesia or liketube with which the supporting wire is sheathed.

To these and other ends, hereinafter set forth, the invention comprisesthe improvements to be presently described, and finally claimed.

The nature, characteristic features, and scope of my invention will bemore fully understood from the following description,

taken in connection with the accompanying drawings, forming part hereof,and in which- Figure 1 is an elevational view of a mantlesupportembodying features of the invention, and Fig. 2 is a sectional viewillustrating a detail of construction.

In the drawings, 1 is a burner top or collar provided with anupwardly-extending holder or tubular socket 2, constituting at its top ashoulder 3.

4 is a refractory tube, as of magnesia, and it is seated on the shoulder3.

5 is a mantle supporting wire rising from the holder 2 and penetratingthe refractory tube 4, by which it is sheathed. As shown, the internaldiameter of the tube 4 exceeds the internal diameter of the wire 5, thusaffording an air-space.

6 is a mantle or incandescent which depends from thehorizontally-arranged upper end of the supporting-wire 5 in such a waythat its skirt hangs below the top of and encircles the top or collar 1.

The refractory tube supported in the position described by the shoulder3 serves to 5o sheath the shank of the mantle-supporting wire. Thus itprotects the latter from the heat of the burner, which in the case ofhighpower lights is considerable. I-Ience the shank of themantle-supporting wire is not heated sufficiently to soften, so that itremains upright and properly supports the mantle in vertical position.The fact that the mantlesupporting wire is prevented from bending, andthus holds the mantle vertically, contributes to the maximum durabilityof the mantle, as the latter lasts longer when held vertically over theburner.

It will be obvious to those skilled in the art to which my inventionappertains that modiiications may be made in detail without departingfrom the spirit thereof. Hence the invention is not limited other thanthe prior state of the art requires; but,

Having thus described the nature and objects of my invention, what Iclaim as new, and desire to secure by Letters Patent, is-

1. A burner-top provided with a shoulder, a mantle-supporting wirerising from the shoulder, and a refractory tube seated on the shoulderand sheathing the wire and of larger internal diameter than the externaldiameter of the Wire so as to afford an air-space, substantially asdescribed. ff-- 2. A-burner-top provided with an upwardlyextendingtubular socket, a refractory tube seated on the top rim of the tubularsocket, and a mantle-supporting wire rising from the interior of thesocket and penetrating the tube whereby the shank of the wire isprotected and reinforced throughout its length, substantially asdescribed.

3. A burner top or cap provided with means for holding amantle-supporting wire, a mantle-supporting wire and a refractory tubesheathing the wire and which is of larger internal diameter than theexternal diameter of the wire so as to afford an air-passage,substantially as described.

In testimony whereof I have hereunto signed my name.

TOWNSEND STITES.
